Information processing device, information processing method, and mapping server

[Object] To improve the convenience of a service using anonymous information. [Solution] Provided is an information processing device including: a real name information acquisition unit configured to acquire real name information from a real name server that stores a user ID and personal information in association with the real name information; an anonymous information acquisition unit configured to acquire anonymous information from an anonymous server that stores an anonymous ID in association with the anonymous information; and a screen generation unit configured to generate a display screen including the real name information and the anonymous information.

Systems and methods for controlling presentation of a menu over a network are disclosed. In one embodiment, an information processing apparatus has a communication unit configured to communicate with an information-providing apparatus over the network, an input unit configured to receive input from a user of the information-processing apparatus, a storage unit storing one or more menus, and a control unit. The control unit is configured to receive, via the input unit, a selection of information for processing, to retrieve, from the storage unit, a first menu associated with the selected information, to receive, via the communication unit, a second menu associated with the selected information from the information-providing apparatus over the network, and to generate a third menu associated with the selected information based on the first menu and on the second menu.

Provided is a data communication method of establishing a plurality of TCP (Transmission Control Protocol) connections between a first information processing device and a second information processing device and communicating each piece of data, which is divided for each prescribed unit, through the plurality of established TCP connections. In the method, the first information processing device dynamically changes the number of TCP connections with the second information processing device by notifying connection-upper-limit information, which represents the upper limit of the number of TCP connections to be established with the second information processing device, to the second information processing device, and by changing the connection-upper-limit information to be notified.

Data communication method and information processing device

The present invention relates to an information processing device and method, and a program that make possible to reduce clock drift that occurs in streaming playback and to perform playback with more stability. An information acquisition part analyzes, using a predetermined method, streams that are held in a buffer, and acquires, as data-amount calculation information, information necessary for calculating a data amount. A calculation part calculates, using the data-amount calculation information, a temporal data amount of the streams that are held in the buffer. A detection part detects, from a result of the calculation, decoder clock drift. When a decoder clock is too fast, a clock control unit controls the decoder clock so that the decoder clock has a speed which is slower than that at present. When the decoder clock is too slow, the clock control unit controls the decoder clock so that the decoder clock has a speed which is faster than that at present. The present invention can be applied to, for example, a communication system.

Information processing device and method, and program

A communication device includes a communication unit that receives a reception window size from a reception side communication device and transmits a packet of a transmission amount corresponding to a transmission window size to the reception side communication device; and a control unit that determines whether a channel with respect to the reception side communication device is in a broad band and high delay circumstance, changes a first state where the transmission window size is a first window size which is not larger than the reception window size to a second state wherein the transmission window size is a second window size which is larger than the reception window size when the channel is determined as the broad band and high delay circumstance, and transmits the packet of the transmission amount larger than the reception window size in the second state.

An information processing apparatus for receiving broadcast data and outputting the received data to a client connected to a network includes a broadcast receiving unit that receives broadcast data; an encryption processor that performs encryption processing on the broadcast data received by the broadcast receiving unit; a data accumulation unit that accumulates encrypted data generated by the encryption processor; a data transmission unit that generates a communication packet in which encrypted data accumulated in the data accumulation unit is stored and outputs the generated communication packet; and a transmission data controller that monitors a retained state of the encrypted data in the data accumulation unit and removes, if a state different from a predetermined allowable retained state is detected, at least part of the encrypted data accumulated in the data accumulation unit from transmission data.

Information processing apparatus, information processing method, and computer program

In a data management method for supervising a non-volatile memory having a plurality of blocks erasable in a lump, each of the blocks being formed by a plurality of pages, each of the pages including a redundant area, the aggregate management information is used for data management to enable prompt booting. The distributed management information, as the management information for the respective blocks, is stored in the redundant area of each page, and the aggregate management information supervises data stored in each block, in a lump, in association with the distributed management information. It is verified, at the time of booting, whether the aggregate management information is effective. The data is supervised based on the aggregate management information when the aggregate management information is effective and, when the aggregate management information is not effective, the data is supervised based on the distributed management information.

Data management apparatus and method, non-volatile memory, storage device having the non-volatile memory and data processing system

A transmitter, a communication system, and a communication method of the same capable of realizing communication of more than a set bandwidth with respect to packet communication with a bandwidth guarantee set therefor by using the set bandwidth as the minimum guaranteed bandwidth, wherein when a transmitter transmits packet data, it decides whether or not packet communication guarantees a bandwidth based on a guaranteed bandwidth set in advance and, when guaranteeing the bandwidth, adds a first identifier to the packet data, while when not guaranteeing the bandwidth, adds a second identifier to the packet data and transmits the same to the network and wherein a relay unit connected to the network decides, in accordance with identifiers registered in advance and guaranteed bandwidths corresponding to same, whether or not the received packet data are bandwidth guaranteed, adds the first or second identifier to the packet data in accordance with the result of the decision, and transfers them to the next relay unit or a receiver side via the network.
